| 摘 要： | ＴＯＸＩ模型是美国环保局的ＷＡＳＰ（水质分析模拟程序）中的一部分。由于该模型考虑了污染物质在河流中溶解态，颗粒态和底泥态的分布关系，对于模拟重金属在河流中的浓度变化效果较好。为保证计算结果的可靠性，首先应对重金属浓度的衰减变化特性进行研究，本文重点讨论的是重金属在河流中迁移转化的过程，并如何将这一过程用数学公式来进行模拟。

| Abstract: | TOXI model is a part of WASP(Water Quality Anaiysis Simulation Program )ftom the United Sates Environmental Protection Agency. Since the medel includee the distribution calcula-tion of pollutants in solution,suspended solid and sediment,so the simulation result for heavymetal is rather good.In order to ensure the simulation result rellable, the change pattern ofheavy metal concentration in river should be studied firstly.It is focal point to discuss themovement and transformation processes of heavy metal in rivers and how to use mathematia;equations expinining these processes. |
